In 2006, the team behind the film, TV series and book released a nonviolent video game developed by Breakaway Games with the same title. The video game was designed to teach the waging of conflict using nonviolent methods. Ivan Marović, one of the leaders of the Serbian student movement called Otpor!, was one of the designers.[8] A turn-based strategy game, it consists of ten pre-built scenarios and an editing system that will allow players to create scenarios of their own.[9]
